My 94 300tdi has suddenly devaloped a wine/hum sounds like its coming from the back. The wine is always present and gets loader with speed. The wine is still present when driving out off gear. This is not the normel t/case wine that i have become accustom too. I have checked diff and t/case oil all fine(no rubber donut on rear tail shaft)Both front an rear shafts are new, one month old. I jacked up all wheels to see if any bearing play seams fine. Only thing that i could see there seams to be a lot of play in the t/case front out-put shaft can be move up or down 1- 2mm is this to much? Has always had this much play in the last two year of ownership. The car has been lifted and runs a double cardan joint im thinking may be the weight off the cardan is putting to much stress on the bearing.I realy wont to fix this noise im very worryed im doing damage. Car has coved 240,00kms if this of any importance.

I have the same humming sound too on my 95 Disco and someone posted way back that i need to check my gears and pinions if its in one piece. It getting worse on highway runs. I have 265-75-16s and 2 in lift. Maybe its a good time to change my gears and pinions to 4.10s and 24 spline shafts. Need help.

Butch,
If you're talking axle shafts & assuming you're running the stock axles, your '95 already has 24 spline shafts from the factory. You can upgrade, however, to a stronger 24-spline shaft.
